DAMPER-REGULATOR.

To all whom it may concern:

- Be it known that 1,.MATINSZAS 1\/IATULA- l'lIS, a citizen of Russia, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Damper-Regulators, of which the following is a specification.

This invention relates to improvements in damper regulators and has asits special object the provision of means whereby the draft of a furnace may be controlled automatically, according to the degree of heat required to produce a substantially constant head of steam within a boiler connected with the furnace.

A furtherobj ect is to provide such devices in forms which may be readily attached to an ordinary type of furnace and boiler with out making a. material change in their construction.

These and other like objects are attached by novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a 1naterial part of this disclosure, and in which Figure 1 is a side elevational view 'indi eating the application of the invention, the view being largely diagrammatic.

Fig. 2 is an enlarged fragmentary vertical sectional view taken through the operating device.

Fig. 3 is a transverse vertical sectional view taken on line 33 of Fig. 2, and,

Fig. 4 is a top plan'view of the same.

Referring to the drawings. the numeral 10 indicates a smoke stack of conventional type, provided with a hood 11, at its top, and in the stack is pivotally engaged a damper plate 12. so that the passage through may be controlled; one of the damper pivots 14, extends through the stack 10, and has rigidly engaged with it a lever 15, pivotally connected by a link 16, to the outer end of a lever 17, pivotally supported at the opposite end on a fixed pin 18.

Arranged to make contact with the lower side of the lever 17 is a plunger rod 20, fixed centrally in a plunger 21, operable within a cylinder 22. into the lower end of which leads a pipe 23, communicating with a casing 24 containing the operative mechanism.

This casing, as will be seen in Fig. 2, is hollow and provided with flanges 25, by which it be secured to any convenient Specification of Letters Patent.

support, the main body 24 of the casing having a cover plate 24 and a gasket or packing 26.

Entering opposite sides of the casing 24, are pipes respectively 28 and 30, thelatter acting as an overflow, discharging into any convenient place, as a sewer opening 31.

The pipe 28 has upon it a valve 32, so the current of steam, entering'from the boiler, with which the pipe 28 engages, may be controlled.

Engaged in the end of the pipes 28, and 30 are sleeves 34, and 34 and'movable in the sleeves are plunger rods35, and 35' the same being in alinement and pivotally joined by pins 36 with the end of a lever 38, these containing openings 39, at their engaged ends through which are drilled small holes 40 and 40 registerable with corresponding holes 41 and-41' formed through the ends of the sleeves 34 and 34 so as to admit the passage of steam therethrough. when the same are in register; I The end of the lever arm 38 is engaged with a spindle 42, which passes through the flanged side of the casing 24, and has connected with it another lever 44, having an outwardly turned arm 45, connected with a link 46 the upper end of which is engaged with a balance lever 47, pivoted on the pin 48 at one end, while its other end has engaged with it a rod '49, supporting adjustable weights 50, the same being adapted to normally draw the lever 47 downwardly.

This lever is raised by a plunger 51, passing through a gage 52, supplied by steam from the pipe 53, direct from the boiler so as to maintain an equilibrium with respect to the weights 50.

From the foregoing it will be clearly apparent that if the lever weights overcome the pressure of the steam from the pipe, the lever will be depressed, and consequently by its connection 53, the lever 38 in the interior of the casing will be moved downward, pressing the plunger 35, into the sleeve 34, so that steam entering from the boiler through the pipe 28, may pass outwardly through the openings 40 and 41 into the interior of the casing, and thence through the pipe 23 to the cylinder 22, raising the piston 21 and by it, the lever 17, closing the damper 12 in the stack, any eX'Cess of steam or water in the casing passing out through the perweights 50, over balance the lever 47, thelatter will be depressed, carrying through its connections the inner lever 38 and opening the damper. v c

Having thus-described my invention what I claim as new and desire to'secure by Letters Patent, is:

' 1. In a damper regulator-of the character described, the combination of a damper with a hollow casing, supply and exhaust pipes communicating with said casing, said supply pipe adaptedto communicate with a source of fluid pressure, a lever pivoted in said casing, a plunger movable in said supply pipe, said plunger having openings permitting the escape of pressure fluid when in a raised position, and means controlled by the action of said lever for operating said damper. i

2. In a damper regulator of the character described, the combination of a damper with a hollow casing, supply and exhaust pipes communicating with said casing, said supply pipe adapted to communicate with a source of fluid pressure, a plunger operable in said supply pipe, said plunger and pipe having openings which may be brought into register permitting a flow of pressure fluid therethrough, a lever pivoted in said casing c11- gaged with the end of said plunger, a

weighted lever adapted to be raised by the pressure of said pressure fluid, operative connections between said weighted lever and the lever within said casing, and operative connections between said damper and said casing whereby when an excess of pressure fluid enters said casing, said damper will be closed.

3; In a damper regulator of the character described, the combination of a damper with a hollow casing, supply and exhaust pipes communicating with said casing, said supply pipe adapted to communicate with a source of fluid pressure, a plunger having a hollow end operably engaged in said supply pipe, alinable apertures formed respectively in said plunger and the end of said pipe with in said casing whereby said casing may be filled with pressure fluid upon an excess of pressure within said source of fluid pressure, a lever in said casing engaged by said plunger, a weighted lever arranged contiguous to said casing, means for raising said weighted lever actuated by the pressure fluid direct from said source, operative connections between said weighted lever and the lever within said casing, operative connections between the interior of said casing and said damper whereby it may be actuated when the pressure fluid is admitted to said casing.

In testimony whereof I have affixed my signature.
